Urban road lighting is one of the focuses of the development of the times. At present, one fifth of the world's electrical energy is used for lighting, and it will continue to increase. How to save energy and reduce emissions has become the biggest problem to be solved in road lighting projects.
Because LED lamps and traditional lamps emit light differently. Traditional lamps emit heat first and then emit light, while the light source accounts for only 8%, the heat accounts for 73%, and 19% is infrared. In the LED light source, 40% of the energy is converted into light, and the remaining 60% is heat.
At least 20% of the world's electricity is used for lighting, but if the light source is not good, not only will more than 30% of the light source be wasted, it will also cause harmful substances to damage the environment.

However, the initial cost is very large, especially when some old venues are refurbished, the cost of labor and lighting is a big investment. So is there a way to get LED lighting and reduce initial costs? The answer is yes, the cheapest way to upgrade lighting is to use the LED Retrofit Kit.
